Answer:

angle L is smallest, followed by angle J, and angle K is largest

Step-by-step explanation:

add all 3 expressions together and set equal to 180 (the number of degrees in a triangle)

2x + 6 + 10x - 11 + 3x - 10 = 180

combine 'like terms'

15x - 15 = 180

15x = 195

x = 13

plug 13 in for 'x' in each expression and ∡L = 29°, ∡J = 32°, ∡K = 119°,
